I have searched and read about the oil catch can here in a couple of articles but I wanted to see what people with a turbo are doing?

The PCV valve goes to the catch can and then does it go back to where it is stock (After the throttle body) or do we have to install it on the inlet that goes to the turbo compressor.

The reason I ask is that when we hit boost.. wont this be doing the opposite of what the PCV system wants... It wants vacume and boost will be reversing the gases.

Does the intake manifold where it connects have a check valve built in or are people installing check valves?

Im about to finish up on my turbo piping and was going to put a hole on my pipe before the turbo to expel the gases from the PCV back into the system and then use the hole that was left open on the intake manifold for my avcr and emanage boost gauge and BOV.

Will this work?? OR does it have a check valve making it pointless?

I've got it connected to the opening on the header. And routed to the air intake pipe.

This allows your engine to carterbreath.

The pcv valve hose should go to the catch can then the other hose should go to the turbo inlet pipe.

You can actually get rid of the pcv valve all together and just run a hose directly from the valve cover to the catch can.

The inlet side of the turbo is constantly pulling vaccum, remember it is sucking. The more boost you make the more vaccum the inlet pulls.

The reason this is the best place is because the more vacuum you create in the crankcase, the better your piston rings seal, and the cleaner your combustion is, hence more horsepower and a cleaner engine internally.
